【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a diagram showing a rear under mirror according to an embodiment of the present invention as viewed from the rear of a vehicle body, FIG. 2 is a perspective view showing the structure of an actuator, and FIG. 3 is a circuit diagram of a control system. In the figure, a back door panel 11 is provided with a rear window 12, and a body 22 of a mirror support body 20 is arranged on a frame body 11a above the rear window 12 of the back door panel 11 via an actuator 21. Has been done. The actuator 21 is fixed in the casing 21a and is capable of rotating the rotating shaft 21b1 in the forward and reverse directions. The motor 21b is a worm gear 21b2 fixed to the rotating shaft 21b1 of the motor 21b. A gear 21c1 meshing with the worm gear 21b2, a rotary cam 21d fixed to the shaft center 21c2 of the gear 21c1, and two microswitches 21e1 arranged at the rotational position of the convex portion 21d1 of the rotary cam 21d. , 21e2.

The casing 21a is fixed to the frame 11a, and the axis 21c2 is fixed to the rear surface of the end of the body 22 of the mirror support 20. The body 22 is formed in a housing shape having semicircles at both ends, and is fixed to the shaft center 21c2 at the center of the semicircular end 22a at one end. The frame body 11a is formed with a recess 11a1 for holding the body 22 in a semi-embedded state at a position substantially horizontal when the body 22 pivots about the axis 21c2 of the actuator 21 as a fulcrum.

Further, the actuator 21 is arranged with the axis 21c2 facing rearward and upward, and when the coaxial center 21c2 rotates counterclockwise within a range of 90 degrees, the other half of the other end of the body 22 is rotated. The circular end portion 22b gradually moves away from the vehicle body. In this embodiment, the shaft center 21c2 is rotatable within a range of about 45 degrees. When the mirror support 20 is in a horizontal state, it is called a storage position. The state where the semicircular end 22b of the support body 20 is farthest from the vehicle body is called a visual recognition position. It should be noted that the micro switch 21e1 of the mirror support 20 comes into contact with the convex portion 21d1 of the rotating cam 21d to turn on when it is in the housed position, and the micro switch 21e2 turns on when it is in the visible position.

The micro switches 21e1 and 21e2 and the motor 21b are connected to a control unit 31, as shown in FIG. The control unit 31 is connected to both ends of the battery 33 via a fuse 32 and is supplied with driving power. An ignition switch 34 is also connected to the positive side of the battery 33, and when the ignition switch 34 is in the position of the accessory ACC, the ignition IG and the starter ST, one end of the backup lamp switch 36 is connected via the fuse 35. Connect to the positive side of 33. The other end of the backup lamp switch 36 is connected to the minus side of the battery 33 via the two backup lamps 37a and 37b, and is also connected to the control unit 31, and the backup lamp switch 36 is turned on. In this case, the backup lamps 37a, 37b are energized and the control section 31 is energized.

The control unit 31 controls energization of the motor 21b according to the on / off state of the backup lamp switch 36. When the backup lamp switch 36 is turned on, the motor 31b is turned on until the micro switch 21e2 is turned off. When the backup lamp switch 36 is turned off, the motor 21b is turned on until the micro switch 21e1 is turned off. An oval convex mirror 22c is supported on the back side of the semicircular end 22b of the body 22, and the angle can be adjusted within a predetermined angle range.

Next, the operation of this embodiment having the above configuration will be described. Normally, the body 22 is housed in the recess 11a1 of the frame 11a as shown in FIG. At this time, the convex portion 21d1 of the rotary cam 21d is in contact with the micro switch 21e1 and the micro switch 21e1 is on. Also, the micro switch 21e2 is off.

When the driver turns on the ignition switch 34 and puts a gear (not shown) in the back, the backup lamp switch 36 is turned on. The backup lamp switch 36 energizes the backup lamps 37a and 37b to turn on the lamps 37a and 37b, and energizes the controller 31 as well. When the controller 31 is energized by the backup lamp switch 36, the controller 31 continues to energize the motor 21b so as to rotate the motor 21b forward until the microswitch 21e2 is turned on while monitoring the on / off state of the microswitch 21e2. When the motor 21b rotates in the normal direction, the gear 21c1 meshing with the worm gear 21b2 starts rotating in the counterclockwise direction, so that the body 22 of the mirror support 20 starts to pivot about the side of the semicircular end 22a as a fulcrum. Due to the pivotal movement of the body 22, the side of the semi-circular end 22b rotates counterclockwise and comes out from the recess 11a1 of the frame 11a to the side of the rear window 12. When the body 22 rotates about 45 degrees as shown in FIG. 5, the convex portion 21d1 of the rotating cam 21d contacts the micro switch 21e2, and the micro switch 21e2 is turned on.

Since the control unit 31 stops energizing the motor 21b when the micro switch 21e2 is turned on, the motor 21b is stopped and the body 22 is maintained in a state of being rotated by about 45 degrees. As described above, since the shaft center 21c2 of the actuator 21 is disposed rearward and upward, when the coaxial center 21c2 rotates and the body 22 pivots, the side of the body 22 opposite to the shaft center 21c2. The semicircular end portion 22b of is separated from the rear window 12. Therefore, when the body 22 is stopped, the lower rear part of the vehicle is reflected on the convex mirror 22c of the body 22 that can be seen from the driver's seat through the rear window 12.

When the driver puts the gear back to the forward side by a predetermined distance, the backup lamp switch 36 is turned off, and the backup lamp switch 36 stops energizing the backup lamps 37a and 37b and sends the backup lamps 37a and 37b to the control unit 31. Stop energizing. Then, the control unit 31 monitors the on / off state of the micro switch 21e1 and continues to energize the motor 21b so as to reverse the motor 21b until the micro switch 21e1 is turned on.

When the motor 21b rotates in the reverse direction, the gear 21c1 meshing with the worm gear 21b2 starts to rotate in the clockwise direction, and the body 22 of the mirror support body 20 pivots in the clockwise direction with the side of the semicircular end 22a as a fulcrum. start. Then, the body 22 gradually rotates from the rear window 12 side toward the concave portion 11a1 of the frame body 11a, and is housed in the concave portion 11a1 when rotated about 45 degrees. Further, since the convex portion 21d1 of the rotary cam 21d abuts the micro switch 21e1 simultaneously with the housing, the micro switch 21e1 is turned on.

Since the control unit 31 stops energizing the motor 21b when the micro switch 21e1 is turned on, the motor 21b is maintained in a state of being housed in the recess 11a1 of the frame 11a. After that, unless the driver puts the gear in the back, the body 22 is housed in the recess 11a1 and does not hinder the rear view during traveling. Further, since it is housed integrally with the frame body 11a, rainwater that splashes the rear wheel does not adhere, and the angle of the mirror does not change due to some rhythm.

In the embodiment described above, the axis 21c2 of the actuator 21 is directed rearward and upward, and the body 22 is taken out from the frame 11a only by rotating the axis 21c2, and at the same time, the body 22 is separated from the rear window 12 by a predetermined distance. Although it is moved to the position, it is possible to move the body 22 between the accommodation position and the visual recognition position while performing more complicated movement by using a plurality of motors or a cam mechanism. You can

Further, in the present embodiment, the accommodation position is in the frame body above the rear window of the back door panel, but it may be in the frame body in the side or the lower part, or instead of the back door panel. It may be on the body side.
